NASA NuSTAR Telescope Showcases Unique X-Ray Images Of Space
2013-08-30 07:47:15

April Flowers for redOrbit.com - Your Universe Online For the first time, NASA’s Nuclear Spetroscopic Telescope Array (NuSTAR) is giving the wider astronomical community a look at its unique X-ray images of the cosmos. NASA’s High Energy Astrophysics Science Archive Research Center (HEASARC) made the first batch of data from the black-hole hunting telescope publicly available on August 29. "We are pleased to present the world with NuSTAR's first look at the sky in high-energy X-rays...

Dwarf Galaxy 'NGC 1232' Caught Ramming Into A Large Spiral
2013-08-14 14:41:32

Chandra X-ray Observatory Observations with NASA's Chandra X-ray Observatory have revealed a massive cloud of multimillion-degree gas in a galaxy about 60 million light years from Earth. The hot gas cloud is likely caused by a collision between a dwarf galaxy and a much larger galaxy called NGC 1232. If confirmed, this discovery would mark the first time such a collision has been detected only in X-rays, and could have implications for understanding how galaxies grow through similar...

Chandra Eyes An Eclipsing Planet
2013-07-30 04:21:13

Lee Rannals for redOrbit.com - Your Universe Online Astronomers using NASA's Chandra observatory were able to witness an eclipsing planet for the first time. A team writing in The Astrophysical Journal said they used the X-ray observatory to detect the exoplanet passing in front of its parent star. "Thousands of planet candidates have been seen to transit in only optical light," said Katja Poppenhaeger of Harvard-Smithsonian Center for Astrophysics (CfA) in Cambridge, Mass., who led...

XMM-Newton's Dance Of The X-rays
2013-07-29 08:36:40

ESA Like car tail lights streaking through a busy city at night, this unique image records over a thousand movements made by ESA's XMM-Newton space telescope as it shifts its gaze from one X-ray object to another. Orbiting in space since 1999, XMM-Newton is studying high-energy phenomena in the Universe, such as black holes, neutron stars, pulsars and stellar winds. Even when moving from object to object, the space telescope collects data. These slews are represented by the bright...

New Record Set By Team From University of Leicester For Cosmic X-ray Sightings
2013-07-23 12:03:43

AlphaGalileo Foundation Exploring the extreme Universe with a rich new resource Three years' research led by University of Leicester Department of Physics and Astronomy Team produces new catalogue with 531,261 detections of X-ray emitting objects - a new record 372,728 unique X-ray sources identified The total area covered on the sky by the combined observation fields is -1400 square degrees Scientists led by the University of Leicester have set a new record for cosmic X-ray...

Life Of Eskimo Nebula Coming To A Beautiful End
2013-07-13 08:19:42

April Flowers for redOrbit.com - Your Universe Online At the end of their lives, stars like our Sun become remarkably photogenic. For example, NGC 2392, located approximately 4,200 light years from Earth, is giving astronomers a beautiful display as it nears the end of its existence. NGC 2392, referred to as a "planetary nebula," has been nicknamed the Eskimo Nebula; however "planetary nebula" is misleading because nebulae have nothing to do with planets. Rather, the term is an...

NuSTAR Observes Dormant Black Hole In Nearby Sculptor Galaxy
2013-06-12 08:35:23

April Flowers for redOrbit.com - Your Universe Online NASA´s Chandra X-ray Observatory caught signs of what appeared to be a black hole eating gas at the middle of the nearby Sculptor Galaxy nearly a decade ago. A new observation by NASA´s Nuclear Spectroscopic Telescope Array (NuSTAR) has found the black hole asleep. Details of NuSTAR´s findings were published in the Astrophysical Journal. "Our results imply that the black hole went dormant in the past 10 years," said...

Black Holes Abundant Early Universe
2013-06-06 14:16:28

John P. Millis, PhD for redOrbit.com — Your Universe Online As telescopes peer into the distant background of the Universe they are, in effect, looking back in time. The light emitted from these objects has been traveling across the Universe for perhaps billions of years. So by analyzing the background light of the sky researchers can get a picture of the composition of the Universe early in its evolution. New data from NASA´s Chandra X-ray Observatory and NASA´s...

Columbia launched from Kennedy Space Center on December 2, 1990 at 1:49 AM EST and landed at Edwards AFB on December 10 at 9:54 PM PST. The shuttle orbited 144 times at an altitude of 190 nautical miles at an inclination of 28.45 degrees and travelled 3.7 million miles. The mission lasted 8 days, 23 hours, 5 minutes, and 8 seconds. The primary objectives were round-the-clock observations of the celestial sphere in ultraviolet and x-ray astronomy with the ASTRO-1 observatory consisting of...

Sample Entry: Astronomy is the scientific study of stars, planets, comets, galaxies, and other phenomena that occur outside Earth's atmosphere (e.g. cosmic radiation). Astronomy deals with the evolution, physics, chemical makeup, meteorology, and motion of celestial objects, and also the formation of the universe. The word Astronomy comes from the Greek words astron (meaning "star") and nomos (meaning "law"). Astronomy is one of the oldest sciences. Since the dawn of man, people always...

X-Ray Astronomy -- Although the more energetic X-rays (E > 30 keV) can penetrate the air at least for distances of a few meters (they would never have been detected and medical X-ray machines would not work if this was not the case) the Earth's atmosphere is thick enough that virtually none are able to penetrate from outer space all the way to the Earth's surface. X-rays in the 0.5 - 5 keV range, where most celestial sources give off the bulk of their energy, can be stopped by a few...

X-ray Pulsar -- This dramatic artist's vision shows a city-sized neutron star centered in a disk of hot plasma drawn from its enfeebled red companion star. Ravenously accreting material from the disk, the neutron star spins faster and faster emitting powerful particle beams and pulses of X-rays as it rotates 400 times a second. Could such a bizarre and inhospitable star system really exist in our Universe? Based on data from the orbiting Rossi X-Ray Timing Explorer (RXTE) satellite,...

Gamma-Ray Burst -- In astronomy, Gamma-ray bursters (GRBs) are flashes of gamma rays that last from seconds to hours, the longer ones being followed by several days of X-ray afterglow. They occur at random positions in the sky several times each day. They are now believed to result from tremendous explosions in far away galaxies, during the creation of a black hole from a dying star or two colliding neutron stars. The black hole, surrounded by a rotating disk of matter falling into it,...
